This invention relates to a machine for attaching rivets to articles andis particularly adapted toattach rivets, constituting contacts, to theporcelain member of a fuse plug.

The object of the invention is to provide a machine of the character setforth which will attach the rivets or contact members to the porcelainmember of a fuse plug rapidly and etliciently and also, without thedanger of injury to the operator of the machine While placing theporcelain members therein.

A. further object of the invention is to provide a machine in which theporcelain member, which is very easily broken, shall not be injured inany way by the attachment thereto of the contact member.

Further objects of the invention will ap pear in the followingspecication.

Like numerals refer to like parts throng out the several views of thedrawings.

In the drawings, 15 is the frame of the machine upon which is journalleda driving shaft-16 driven by a pulley 17 and having a pinion 18 fastenedthereto, which meshes into a gear 19 formed on the periphery of onemember 20 of a clutch 21. The member 2O is rotatably mounted upon ashaft 22, while another member 23 of the clutch 21 is keyed to the shaft22. Normally the clutch member 20 rotates loosely upon the shaft 22, butwhen a locking member 24 of the clutch is released by moving a slide 25toward the right, Fig. 5, the locking member 24 locks the two parts 20and 23 of the clutch together and thus the shaft 22 is rotated in theusual well-known manner. The slide 25 is moved toward the right by alever 26 and pawl 27 which are rocked upon a pivot 28 by an arm 29 whichis connected by a rod 30 to a treadle not shown in the drawings. Aspring 31 moves the slide 25 to the left, Fig. 5, when the treadle isreleased, whereupon the slide will be engaged by the locking member 24of the clutch and the two members 23 and 20 thus disengaged from eachother, they yshaft 22 coming to a stop and the member 20 continuing itsrotation thereon.

A plurality of anvils 32, 33, 34, 35, 36, 37, 38 and 39 are mounted upona turntable 40.

These anvils are duplicates of each other and each is provided with ashank41 which projects downwardly through a sleeve 42, see Fig. 10, andis fastened to said 'sleeve by `a pin 43. The sleeve 42 projects.through ya tened to the lower portion thereof, and theturntable,together with the ring 49 which forms a portion thereof, rotates withina recess 50 provided in a cover 51. The cover 51 is supported upon andfast to the bracket 47.

- It is very necessary that the working parts,

namely, the turntable and the mechanism by which it is intermittentlyrotated, should be provided with covers to keep the dust which comesfrom the porcelain member from ooming into contact therewith. Theturntable 40 is horizontally disposed and has a vertical shaft 52projecting downwardly therefrom into the bracket 47 in which it isrotatably mounted. l

An'intermittent rotary movement is iinparted to the turntable 40 by themechanism specifically illustrated in Figs. 2 and 4 and consisting of apawl 53 which is pivoted at 54 to a slidel 5'5. The actuating pawl 53has a tooth 56 thereon which, when the pawl is in operation, projectsinto one of a series of recesses 57 in the periphery of the turntable40. The turntable after being rotated through one-eighth of a rotationis locked in position byv a locking pawl 58 which is pivoted at 59 tothebracket 47 and is provided with an arm 60, the end 61 of which engages aroll 62 rotatably mounted on a pin 63 fast to the slide 55. Theactuating pawl 53 and locking pawl 5 8 are pressed against the peripheryof the turntable 40 by arms 64 and 65 respectively. These' arms arefastened to rotatable studs 66`an'd 67 and these studs have pins 68 and69 proj ecting therefrom which are connected together by a spring 70.

A reciprocatory movement is imparted to Athe slide 55 by the mechanismillustrated in Fig. 2 inr which a link 71 is pivotally connected at 72to an ear 73 on the slide 55, the other end'of the link 71 beingpivotally connected at 74 to an arm 75 of a lever 7 6 which is pivotedat 77 to the frame 15 of the machine. Another arm 78 of the lever 76 isconnected by a pin 79 to a link 8O through the lowerI end of which acrank pin 81 projects, the' said crank pin being adjustably fastened ytoa crank plate 82 by a nut 83. The crank plate 82 is'fastened to theshaft 22. The crank plate 82 rotates in the direction of' the'arrow athereon and thus imparts a rocking movement to the lever 7 6 through thelink which, in turn, imparts a rel ciprocatory movement to the slide 55through thelink 71.

Assuming the slide to be moved toward the right, Fig'. 4, it will beseen that the actuat-4 ing pawl 53 willmove the turntable in thedirection of the arrow b and during this rotation the locking pawl 58will be released by the roll 62, so that it bears against the peripheryof the turntable 40. When the turntable has been moved one-eighth of arotation, a* tooth 84 on the, lockingfpawl 60Vwill drop into one of thelrecesses 57 in the periphery of the turntable and lock the turntable inposition ready for a rivet to be set.

Each of the anvils has a spring 85 encircling the same, see Fig. 10,resting at its lower end on a flange 86 on the upper end of the sleeve42. The spring 85 projects into a chamber 87 in an article support 88,the upper end of the Spring bearing against an annular flange 89provided in the tubular part 88 and slidable upon the shank 41 of theanvil. The anvil is provided with a shoulder 90 which engages the upperace et the flange 89. The article support isprovided with a plurality ofprongs 91, preferably three, and upon these prongs the article 92, inthis case the porcelain memberA of a fuse plug, rests as illustrated inFig. 10.

The rivets 93 are fed from a hopper 94 to a raceway 95 and the lowermostone of a column of rivets on said raceway is separated from the rest ofthe rivets in the column and allowed to move by a reciprocatory slide96, Figs. 1 and 10, to the position of the rivet 9 3 in a manner wellknown to those skilled in this art, whereupon it will slide down thelower part of the raceway until the headl 97 of the rivet rests againstthe side of a rivet driver 98 as illustrated in Fig. 10.

The rivet driver 98 has a reciprocatory inotion imparted thereto, seeFig. 3, by a lever 99 to which it is connected by a pin 100. The lever99 is pivoted at 101 to a rocker arm 102 which, in turn, is pivoted at103 to they frame 15 of the machine. rlhe lever 99 has an arm 104pivoted thereto at 105. This arm projects through a bifurcated guideplate 106 and is fastened thereto by a screw 107. A pin 108 extendsacross the bifurcated guide plate 106 from one side to the other thereofand above the upper edge of the arm 109 of the lever 99. A stop screw110 has screwthreaded engagement with the rear end of the arm 109, itslower end bearing against i a disc 111 which has a projection 112thereon projecting into a spiral spring 11.3. The spiral spring 113 ispositioned in a hole eX- tending through the arm 104 and rests at itslower end against a plate 114 fast to the lower edge of the arm 104. Theupper end of the i spring 113 bears against the disc 111, so that anyupward pressure exerted by the arm 104 will be transmitted to the lever99 with a yielding pressure, dueto the spring 112.

A spring 115 connects the arm 104 to an eye 116 fast to the frame of themachine. The arm 104 is connected by a pin 117 to.. a link 118 which, inturn, is pivotally mounted at its lower end upon a crank pin 119 on alas crank `which is fastened to the shaft 22. It will be seen that asthe shaft 22 rotates, the crank 120 and crank pin 119 through the link118, will cause the arm 104 and the lever 99 to rock about the pivot 101and thus impart a reciprocatory motion to the driver 98 which is inalignment with one of the anvils, as 32, when the parts are in theposition illustrated in Fig. 4.

' A rivet carrier 121, Fig. 10, consists or two blocks 122 with achamber 123 therein. These blocks are each mounted upon a flat spring124 and the upper ends of the iiat springs are fastened to a slide 125.4The slide 125 has mounted therein Aan arm 126 pivoted on a pin 127. Thelower end 128 of said arm projects into the chamber 123 between the twoblocks 122 in readiness to receive a bifurcated rivet, such as 93, thuslining the rivet up in the particular location relatively to the article92 into which it is to be inserted. A spring 129,'positioned in theslide 125, bears against the rear edge of the arm 126 and holds it inthe position illustrated in Fig. 10 until said arm is forced back, ashereinafter described. A screw 130 is fastened to the upper end of theslide and projects through and above the frame, and a spring 131encircles the screw and bears at its upper end against the head 132 ofsaid screw, whereby the slide 125 is moved upwardly. A stud 133 isfastened to the frame 15 and projects downwardly through the slide 125,being provided with a head 134 and thus constituting a stop 1 to limitthe distance to which the slide 125 can be moved downwardly.

Assuming the parts to be in the relative positions illustrated in Fig.`10, the driver 98 will iirst be moved upwardly until the lower endthereof clears the head 97 of the rivet 93, whereupon said rivet willfall down into the chamber 123 in the rivet carrier 121 and the lowerend 128 of the arm 126 will project into the slot in the rivet shank asillustrated in Fig. 11. It will be noted that the flange 97 of the rivet93 rests on the bevelled upper edge of the blocks 122. Now when thedriver 98 descends, it will engage the head 97 of the rivet 93 and pushsaid rivet together with the 'blocks 122 and slide 125 downwardly, thuscarrying the arm 126 downwardly until the slide 125 engages the head 134of the stud 133. Further downward movement of the driver will then causethe arm 128 to be swung backwardly and the rivet 93 will be pushed outfrom between the blocks 122 and inserted in the fuse member 92 with theprongs spread apart by the anvil 32, as illustrated in Fig. 12. Therivet driver 98, the carrier 121 and the arm 126 will then return to therelative positions illustrated in Fig. 10. The turntable will then berotated by the mechanism hereinbefore set forth one-eighth of a rotationin the direction of the arrow bringing the anvil 32 into the position ofthe anvil 33, Fig. 4, and upon the next cycle of movements the anvil 32will be moved oneeighth of a rotation to the position of the anvil 34,Fig. 4. When in thisl position the anvil will be in alignment with anarticle remover which will operate to remove the fuse plug member 92with its contact rivet 93 from the anvil. 32.

The article remover 135 is illustrated in Figs. 2, 6, 7 and 8 andconsists of a holder 136 and upwardly extending shank 137 upon which apair of jaws 138 and 139 are pivotally mounted at 140 and 141. Thesejaws are positioned in slots 142 and 143 in the holder 136 and arepressed toward each otherby a U-shaped spring 144, the ends of whichproject into holes provided therefor in the jaws 138 and 139. Stops 145and 146 limit the distance to which these jaws may be moved toward eachother, as illustrated in Fig. 6. The lower free ends of the jaws 138 and139 each terminate in an arcuate flange 147 and each of these flangeshave a ledge 148 projecting inwardly therefrom, as illustrated in Figs.7 and 8. These ledges are bevelled downwardly and outwardly along theirfaces 149 from the upper edge 150 of said ledge. The front ends 151 ofthe flanges 147 are spaced apart and are bevelled on their inner facesat- 152, particularly as shown in Fig. 7 so that after being removedfrom the anvil the article 92 may fall out of the jaws 138 and 139. Itwill be understood that the article remover 135 is in alignment with oneof the anvils and as each anvil is moved by the turntable to theposition of the anvil 34, it will be brought into alignment with thearticle remover 135. 1

' In order to remove the article 92 from the anvil and holder uponwhichit is positioned, it is necessary to impart a reciprocatory motion tosaid article remover and this is accomplished by the mechanismillustrated in Fig. 2 by a lever 153 pivoted at 154 to the frame of themachine and engaging a collar 155 on the shank 137 of the holder 136. Arocking motion is imparted to the lever 153 by a link 156 pivotallyconnected to the rear end thereof by a pin 157, the lower end of thelink 156 being connected by a pin 158 to a lever 159 pivoted to theframe at 160 and 'having a cam roll 161 rotatably mounted on its rearend and engaging the cam-shaped periphery of the crank plate 82. Aspring 162`holds the cam roll 161 in engagement with the cam-shapedperiphery of said crank plate 82.

When the article remover 135 is moved downwardly by the mechanismhereinbefore described the bevelled faces 149 of the flanges 147 on thejaws 138 and 139 `will engage the iiange 163 on the fuse plug member 92and will slip over it. The jaws will then be brought together beneaththe flange 163 `and 'when the remover is moved upwardly the upper edges150 of the ledges 148 will engage the under face ofthe flange 163 andlift the fuse plug member 92 olf of its support 88- and off of the anvil32, whereupon the article will fall outwardly through the space betweenthe ends 151 of the flanges 14'?.

The general operation of the mechanism hereinbefore specifically and toa considerable extent in general described is as follows: --The operatorplaces an article such as a fuse plug member 92 upon any one of theanvils and the respective article supports positioned at 35, 36, 37 or3S. The turntable is then rotated in the direction of the arrow b, Fig.4, until each of the anvilsy is brought successively into alignment withthe rivet setting mechanism and with the article removing mechanism, andwhile the turntable is locked in position by the locking pawl 5S a rivetis inserted and clinched in one of the articles at the position of 32,Fig. 4, and an article is removed at the position of 34, Fig. 4.

Fig. 9 illustrates an anvil and article support for a porcelain fusemember of a different design from the porcelain fuse member 92V and inFig. 9, 40 is the turntable, 44 the tubular support, 32 the anvil, 41the shank of the anvil, the spring and 88 the article support. Theoperation of setting the rivet in the article 92 is the same ashereinbefore described with relation to the setting of the rivet intheporcelain fuse member 92.
